Report review and sign-out by: Beth Dye Applications Manager (Hazardous Substances). 3.3 The applicant supplied the following documents: the application; and confidential appendices including formulation data, supplementary commercially sensitive details regarding the substance’s lifecycle and presentation, the OECD SIDS document for dicyandiamide, ACVM approval documents and background documentation on soil nitrification losses. 3.4 The following government departments were advised of the receipt of the application (in accordance with clause 2(2)(e)) and given the opportunity to comment: the Department of Labour (Workplace Group); the New Zealand Food Safety Authority (Agricultural Compounds and Veterinary Medicines Group (ACVM Group)); and the Ministry of Health. 3.5 No responses were received. 3.6 A request for more information was issued under section 58 of the Act on 03 August 2007. The requested information was supplied on 09 August 2007. The information supplied was reviewed and considered sufficient to proceed with the assessment. 3.7 The applicant was provided with a copy of the proposed controls for AgResearch dicyandiamide device and given the opportunity to comment on them. The comments provided were taken into account in the setting of controls. 4 Consideration Sequence of the consideration 4.1 This application was considered by the Chief Executive of ERMA New Zealand under delegated powers from the Authority (section 19(2)(e)). 4.2 In accordance with section 32, the approach adopted when considering this application was to confirm whether the application was for one of the purposes specified in section 30, to identify and assess the risks and to determine whether the substance ERMA New Zealand Decision: Application HSC07017 Page 2 of 9 could be adequately contained by controls to provide for each of the matters specified in Part III of the Third Schedule of the Act. Purpose of the application 4.3 The purpose of the application is to enable AgResearch Limited to manufacture and field trial a slow release device containing dicyandiamide (DCD). The trials will be conducted to optimise the release rate of the carrier matrix and determine the quantity of DCD required to effectively inhibit nitrogen leaching from soil urine patches of grazing animals. 4.4 The Project Team considers that the purpose of the application amounts to “research and development” on the identified substance and therefore the application qualifies for consideration under section 30(ba). Lifecycle 4.5 The applicant, AgResearch Limited has stated that the DCD component of the device will be imported into New Zealand and the slow release admixture will be formulated by Argenta Limited, an Auckland based company. The blending of the admixture and the DCD will also be carried out by Argenta Limited. The concentration of DCD in the trial substance will vary between 25 and 70 percent weight by weight (w/w). 4.6 The applicant intends to trial the substance, primarily, at their Palmerton North and Hamilton research centres. Field trials will also be carried out at various AgResearch farms and other farms contracted to AgResearch throughout New Zealand. 4.7 The substance will be applied into urine patches of grazing livestock, some of which may be food producing. Due to the novel nature of the application technique being used detail has not been released by the applicant for commercial reasons. For assessment purposes details are provided in confidential Appendix 2. The substance’s presentation and application technique are expected to limit human exposure to the substance. 4.8 The applicant has indicated that the application of DCD into the environment will be significantly less than that applied when DCD is used conventionally, i.e. broadcast application as a slurry or granule. 4.9 Any unused quantities of the substance will be returned to AgResearch Limited at the completion of the trials. Hazardous properties 4.10 The Project Team notes that a containment application only requires sufficient understanding of the hazardous properties to ensure that any risks can be managed by the containment controls. The scope of the hazard information will often be limited for containment applications, as the substance will be experimental and data on its hazardous properties may not be available. 4.11 The applicant has provided an assessment of the hazards posed by DCD but not for the formulation as a whole. The Project Team notes that the hazards posed by DCD ERMA New Zealand Decision: Application HSC07017 Page 3 of 9 are reasonably well understood and the component is covered by existing approvals in New Zealand. While DCD only triggers hazard classifications for ecotoxicity the Project Team notes that another component in the formulation triggers a range of both toxicity and ecotoxicity classifications. Given the lack of data on the formulation and the hazard thresholds triggered by individual components the Project Team considers that the substance has the potential to cause adverse affects within the environment and to human health. 4.12 The Project Team has reviewed the information supplied by the applicant and other information available to it and considers that there is sufficient information to determine that any risks posed within the defined lifecycle of the substance in New Zealand can be adequately managed through the application of controls. Identification and evaluation of the significant risks of the substance in containment 4.13 The applicant has identified and assessed potential risks and detailed proposals for, and impacts of, risk management. The Project Team has reviewed the applicant’s assessment of the risks to the environment, human health and welfare and Māori issues and concerns as set out below: Risks to the environment 4.14 If released into the environment, the substance has the potential to result in adverse effects within the environment. 4.15 On the basis of the lifecycle of the substance, adverse environmental effects could arise from: an accident during storage, use or transportation, resulting in release of the substance; failure to follow the correct operational procedures as set out in the controls and containment system as described in the application, resulting in release of the substance; or failure to follow correct disposal procedures. 4.16 The Project Team notes that limited quantities of the substance will be manufactured and released into containment for field trials (i.e. up to 100 litres or kg depending on the substance’s physical form). The Project Team also notes that DCD may, at present, be applied in bulk as a fertiliser additive to pasture. 4.17 The Project Team considers that, taking into account the hazardous properties of the substance, the quantities involved, the containment controls in Appendix 1 and controls in place under other legislation, there are no significant risks to the environment from this trial. Risks to human health and welfare 4.18 The Project Team considers that adverse effects to human health and welfare may result from exposure(s) to the substance, given the level of detail provided and the related uncertainty. ERMA New Zealand Decision: Application HSC07017 Page 4 of 9 4.19 On the basis of the lifecycle of the substance outlined in paragraph 4.5-4.9, adverse effects could arise from: an accident during storage, use or transportation, resulting in release of the substance; failure to follow the correct operational procedures as set out in the controls and the containment system, resulting in personnel exposure while contained, or bystander exposure if released; or failure to follow correct disposal procedures. 4.20 The Project Team notes that the substance’s presentation is expected to reduce the potential for human exposure during its handling; however, exposure is still possible during its manufacture and packaging. 4.21 The Project Team considers that there are no significant risks to human health and welfare, given the likely properties of the substance, the quantities involved, the containment regime proposed by the applicant, the containment controls in Appendix 1 and controls in place under other legislation. Māori issues and concerns 4.22 The Project Team has considered this application in accordance with clauses 9(b)(i) and 9(c)(iv) and sections 6(d) and 8. In addition, the Project Team used the framework contained in the ERMA New Zealand user guide “Working with Māori under the HSNO Act 1996” to assess this application. 4.23 In its assessment the Project Team has not identified any likely impacts that this substance could have on Māori in terms of culture, traditional relationships with ancestral lands, water, sites, wāhi tapu, valued flora and fauna or other taonga. The Project Team has no evidence to suggest that the controlled containment trial use of the substance will breach the principles of the Treaty of Waitangi and therefore sees no requirement for the applicant to consult with Māori regarding this application. 4.24 This assessment is made on the condition that the substance is handled, blended, stored, transported, used and disposed of, in accordance with the explicitly stated HSNO controls, and any controls stipulated in other applicable Acts. However, should inappropriate use, or an accident, result in the contamination of water bodies or the environment, it is suggested that the applicant notify the appropriate authorities including the relevant iwi authorities in that region. This action should include advising them of the contamination and the measures taken to contain and remedy it. 5 Containment and controls 5.1 The Project Team has evaluated the adequacy of the containment arrangements proposed by the applicant and the controls listed in Appendix 1, and notes that these cover the matters set out in Part III of the Third Schedule of the Act, being: to limit the likelihood of escape of any contained hazardous substances or contamination by hazardous substances; to exclude organisms from a facility; to exclude unauthorized people from the facility; ERMA New Zealand Decision: Application HSC07017 Page 5 of 9 5.2 to prevent unintended release of the substances by experimenters working with the substance; to control the effects of any accidental release of the substance; inspection and monitoring requirements; and qualifications required of the person responsible for implementing the controls. The Project Team is satisfied that, with adherence to the controls listed in Appendix 1 and those controls in place under other legislation, AgResearch dicyandiamide device can be adequately contained. 6 Decision 6.1 I have considered this application made under section 31 and, pursuant to section 32, I am satisfied that this application is for the purpose specified in section 30(ba). 6.2 Having considered the risks associated with the lifecycle of AgResearch dicyandiamide device, I am satisfied that the controls imposed, including those in place under other legislation, will result in the substance being adequately contained. 6.3 In accordance with clause 36(2)(b), I record that, in reaching this conclusion, I have applied the criteria specified in section 32. 6.4 I have also applied the following criteria in the Methodology: clause 9 – equivalent of sections 5, 6 and 8; clause 11 – characteristics of substances; clause 21 – the decision accords with the requirements of the Act and regulations; clause 22 – the evaluation of risks – relevant considerations; clause 24 – the use of recognised risk identification, assessment, evaluation and management techniques. 6.5 The containment application to import or manufacture the substance identified as, AgResearch dicyandiamide device, for the purposes of research and development is thus approved pursuant to section 32, with controls set out in Appendix 1. 13 August 2007 Rob Forlong Date: Chief Executive of ERMA New Zealand Substance Identifier ERMA New Zealand Approval Code: AgResearch dicyandiamide device HSC000281 ERMA New Zealand Decision: Application HSC07017 Page 6 of 9 Appendix 1: List of controls that apply to the hazardous substance AgResearch dicyandiamide device Scope 1.
